(Cl. lit-135) 1 Claim.

This invention relates to an improved type of hinge, intended to be usedon kitchen cabinets or similar articles of furniture having a door orclosure member for shelves or other compartments.

A primary object of the invention is to provide a hinge which may beeasily and readily fitted to the door frame and the door, in such amanner that when the door is swung open, it will move outward for adistance equal to or greater than its own thickness,'so that the doorwill substantially clear an adjacent door of equal thickness on thecasing or frame adjoining the hinged edge thereof. That is to say, it isproposed to provide a hinge wherein the pintle is located relativelyremote from the attaching arms of the leaves, namely, substantially atthe outer face of the door. Moreover, a hinge of the type set forthherein, may be applied to a door which is mounted fiushly over the dooropening of the 7 frame, Without the necessity of rabbeting the doorframe, thus involving less shop work in the mounting of the door and atthe same time, enabling the upper and lower corners of the door to beshaped or molded as desired, thus lending itself to the design orornamental characteristics of the cabinet or case to which it is fitted.

With the above and other objects in view which will be more readilyapparent as the nature of the invention is better understood, the sameconsists in the novel construction, combination, and arrangement ofparts hereinafter more fully described, illustrated, and claimed.

A preferred andpractical embodiment of the invention is shown in theaccompanying drawing in which:

Fig. 1 is a detail perspective view of a door closed on a casing andincluding the present hinge.

Fig. 2 is a detail perspective view similar to Fig. 1 showing the dooropen.

Fig. 3 is a detail top plan view showing how the doormay be opened whentwo casing units are mounted in abutting relation.

Fig. 4 is a fragmentary side elevation showing the hinge in closedposition.

Similar reference characters designate corresponding parts throughseveral figures of the drawing.

According to the embodiment shown, the same includes a hinge designatedgenerally as A, adapted to be applied to the door. B which covers theopening in a cabinet or case C. The cabinet C preferably includes a doorframe C which is completely covered by the door B whose upper end may berounded or otherwise ornamentally formed as indicated at B the dooritself being provided at one edge with a slot or kerf B foraccommodating the knuckle portion of the hinge which will now bedescribed more in detail. As will be seen from Fig. 1 the edge of thedoor B is flush with the side wall of the cabinet C.

According to Fig. 3, the hinge A preferably includes a pair of leafplates each of which arev of right angular form, thereby to provide theattaching arms I and 2 and. the knuckle arms 3 and 4. The attaching armsI and 2 are provided with suitable openings for receiving screws orother fastenings, and, as will be seen from the drawings, when the hingeis closed, the said attaching armsare disposed in opposite co-planarrelation, while the knuckle arms are in juxtaposed registering relation.

The attaching arms l and 2 are intended to be secured directly to theface of the casing 01' frameC and the inner face of the doorrespectively. Also to avoid binding of the attaching arms or the innercorner of the door on the face C of the door frame, when the door swingsopen, the edge a: of each attaching arm adjacent the outer right angularedge 1 of each knuckle arm is cut away to provide the clearance 2. Inother words the edge at of each attaching arm is located inwardly of theplane of the side wall of the cabinet 0 as well as the edge of the doorB which is flush with the side wall.

The knuckle arms 3 and 4 are preferably of substantially triangularformation, that is, in the form of a right angle triangle, wherein oneof the right angular sides of the triangle is connected with its relatedattaching arm and the other right angular side is, as above described,preferably offset from or disposed outwardly of the side edge of saidrelated arm, while the hypotenuse of the triangle is located at theinner side of the hinge. The knuckle arms 3 and 4 are connected by apintle 5 located in the included angle ofthe triangle which is remotefrom the attaching arms I and 2. Thus, in the embodiment shown, it willbe clear from Figs. 1 and 2, that the axis of the pintle 5 is locatedsubstantially in the plane of the outer face of the door B.

When the hinge A, having the features above described, is mounted orapplied, the attaching arm I may be secured to the outer face of thedoor frame C while the attaching arm 2 is fastened to the inner face ofthe door B, without the necessity of mortising in either case, and thejuxtaposed knuckle arms, which form the knuckle of the hinge, arelocated in the slot or kerf B previously referred to. The slot is cutthrough the inner face and one edge of the door and part ly into theouter or front face of the door while the bottom of the slot is inclinedto substantially the same angle as the hypotenuse of the triangularknuckle arms.

It will of course be understood that as many hinges A may be applied tothe door B, as desired or required, all of said hinges, however, beingmounted as described.

When the door is opened, it will pivot on the pintle 5, and because theaxis of the pintle is located outwardly of the face of the door frame,for example, substantially in the plane of the outer face of the door,the inner comer of the door, will not bind against the face C of theframe of the cabinet in moving to open position because the edge a: ofthe attaching arm I is located inwardly of the edge u of the knuckle arm3, and moreover, the door A will also substantially clear the free edgeof the adjacent door B of an adjacent cabinet C, which may be closed, asshown in Fig. 3.

As will be apparent from the drawing, each leaf of the hinge is bentinto right angular formation to provide an attaching arm and a knucklearm, and when the leaves are assembled by the pintle 5, thecorresponding faces of the knuckle arms will be in substantiallyabutting relation. That is to say, the face of the knuckle arm 3 whichis lowermost, when the hinge is installed in a vertical position, willbe adjacent to the upper face of the knuckle arm 4, therebydistinguishing the present arrangement from hinges wherein the top faceof one knuckle arm would engage the bottom face of the other knucklearm.

The individual hinge leaves are duplicates of each other and whenreversed to be assembled in the order shown, have their attaching arms Iand 2 respectively disposed in opposite directions.

This arrangement is important since when the hinge is closed, theattaching arms I and 2 will lie in co-planar relation instead ofparallel abutting relation, as would be the case if the attaching arms Iand 2 were not oppositely disposed. If the arms were disposed in thesame direction to lie in parallel abutting relation, the door would beunduly offset from the face of the cabinet when the hinge is closed.

I claim:

A door mounting for cabinets adapted to be placed in side by siderelation, with the door frames lying in a common plane, and each havinga door coextensive with the frame, each door having a slot in one edgeat a hinge location, a door hinge comprising a pair of leaf plates ofright angular form to provide attaching arms and knuckle arms, saidattaching arms being disposed in opposite directions and one arm beingattached directly to the outer face of the door frame and the other armbeing secured directly to the inside face of the door, and, when thedoor is closed, said attaching arms lying in co-planar relation, saidknuckle arms being in the form of right angular triangles adapted to bedisposed in superimposed registering relation when the door is closedand lying in said slot, one of the right angular sides of eachtriangular pintle arm being connected with its related attaching arm andthe other right angular side being disposed outwardly of the side edgeof said related attaching arm, and a pintle connecting said knuckle armsand located in the included angle thereof remote from said attachingarms, the axis of the pintle lying substantially in the plane of theouter face of the door, whereby said door when swung through an arc ofapproximately will clear the swinging edge of a closed door on anadjacent cabinet and fiushly overly the same.
